These equations describe the state of the atmosphere -- everything from temperature, to humidity, to wind speed, to convection --...

NASA's terra.nasa.gov Terra spacecraft has assembled the most complete view ever of the world's air pollution traveling through the atmosphere, across continents and oceans. For the first time, policymakers and scientists now have a way to identify the major sources of air pollution and to closely track where the pollution goes, anywhere on Earth. The false colors in these images represent levels of carbon monoxide in the lower atmosphere, ranging from about 390 parts per billion (dark brown...

This true-color scene is situated along Antarctica's Scott Coastline (toward the west, or lefthand side, of the image), looking out toward the Ross Sea (eastward, or toward the right). Near the top of the image, the Drygalski Ice Tongue juts eastward roughly 80 km (50 miles) out from the coast. Just below this ice tongue is a cluster of large icebergs surrounded by a large bed of sea ice. The large, coke bottle-shaped iceberg toward the lower right was named B-15 by scientists; it captured the...

Satellite remote sensors view the Earth at many scales of space, ranging from global through continental, regional, and local--even observing details as small as one meter (three feet) across. These data enable scientists to study a wide range of phenomena that occur over these same scales of space, such as El Nino, droughts, storms, and flash floods. The above image shows the Hollywood sign above Los Angeles, California. It is the final frame in an...
